OK - theoretically speaking:

You can get 6 dB (= 4 times) extra output by using two instead of one bass unit. 3 db from the extra sensitivity gained from better acoustic loading of the units, + 3 dB from the doubled power handling - in all, 6 dB.

But why not build two? Then you have a stereo pair & will then be able to go higher in crossover frequency if necessary...
